There's not much surprise left to LG's Optimus G Proreveal set for next Wednesday in New York. We've already seen the device slip through the FCC and recently had a previewed glimpse of the potential hardware. But thanks to a trusted source, we now have more insight into the the upcoming AT&T variant's specifications. Based on the official doc we had a look at, LG's managed to keep this US model mostly in line with its global sibling, porting over the same 5.5-inch form factor, 3,140mAh battery, 1.7GHz Snapdragon 600 processor paired with 2GB RAM, a healthy 32GB of internal storage (expandable via microSDXC to 64GB), 2.1-megapixel front-facing / 13-megapixel rear cameras, NFC and WiFi a/b/g/n. What has changed is the actual screen technology used: the AT&T G Pro employs a Full HD IPS panel as opposed to the True HD-IPS+ in the original. Additionally, and unsurprisingly, the device's radios have been tweaked, with the AT&T G Pro now supporting the carrier's flavor of LTE (700/1700 MHz), HSPA+21 (850/1900/2100 MHz) and quadband GSM (850/900/1800/1900 MHz).

Though it would be nice to see LG bump this up to a more current version of Android -- namely, 4.2.2 -- the AT&T model will likely ship with the more dated 4.1.2 Jelly Bean. Continuing further down the software track, carrier bloat looks to be at a minimum as only two automobile-specific apps are mentioned in the document: AT&T DriveMode and Navigator. Aside from that, LG's own software suite makes the transition, bringing along QSlide 2.0 (a multiwindow feature), Dual Recording (for the picture-in-picture effect), Tag+ for NFC, VuTalk (a note sharing app), QuickMemo, Notebook and the ability to preset the Home Key's LED. That enough of a preview for you? Stay tuned for the formal unveiling next week.
